Case in brief
A 29-year-old woman with irregular menses had extremely high β-human chorionic gonadotropin levels and ultrasonographic findings suggestive of ectopic pregnancy. Laparoscopic exploration identified a hemorrhagic mass involving the right fallopian tube and pelvic sidewall. Histopathology established primary tubal choriocarcinoma with pelvic peritoneal implantation, classified as FIGO stage III. She received multiple cycles of 5-fluorouracil plus actinomycin D; serial β-human chorionic gonadotropin levels normalized within 2 months, and she remained in sustained remission during follow-up.
What made this case unusual
The tubal choriocarcinoma presented with findings suggestive of ectopic pregnancy and had pelvic peritoneal implantation, making histopathology essential to distinguish the malignancy from the suspected diagnosis.
Diagnostic / clinical pearl
When suspected ectopic pregnancy is accompanied by a tubal mass, histopathological examination may be necessary to establish or exclude primary tubal choriocarcinoma.
